Boeing Jet Marketing Chief to Retire

Duties Will Be Split Between Sales and Finance Units

The head of marketing for Boeing Co.'s commercial airplanes division is retiring and the company is reorganizing its marketing and business development organizations.

Mike Bair, a 34-year veteran of the Chicago-based aircraft maker, will step down on Nov. 1. Ray Conner, chief executive officer of commercial airplanes, disclosed the move on Thursday in a memo to employees that didn't give a reason for Mr. Bair's retirement.
